Presented work is focused on modelling of the phase transformation during laminar cooling after hot rolling of dual phase steel strips. Conventional FE model describing heat transfer was used in the macroscale. The model based on the solution of the diffusion equation with moving boundary was selected to predict properties of the steel based on phase transformations which occur in microscale. Preliminary observations indicated that results depend on various parameters of the model, such as: diffusion coefficient, boundary velocity factor and cooling rate. Therefore, sensitivity analysis of the model with respect to these parameters was performed in order to enhance the predictive capabilities of the model and to simplify further solution.
